CLEAN-OUT TRAP FOR RANGE-CLOSETS.

SPECIFICATION forming part of Letters Patent No. 598,899, dated February15, 1898.

Application filed April 9, 1897. Serial No. 631,474. (No model.)

T0 at whom it may concern.

Be it known that I, J OSEPH H. BRADY, a citizen of the United States,residing at Kansas City, in the county of Jackson and State of Missouri,have invented certain new and useful Improvements in Clean-Out Traps forRange-Closets; and I do hereby declare that the following is a full,clear, and exact description of the invention, such as will enableothers to make and use the same, reference being had to the accompanyingdrawings, forming a part of this specification' My invention has for itsobject, primarily, to cause the rapid discharge of the sewage from thedischarge-basin in a latrine immediately after flushing the basins;second, to enable the water in the discharge-basin to be lowered indegrees, and, third, to afford a free passage of the floating materialwhen the trap and valves ,are'raised in position.

My invention consists in the novel construction and combination ofparts, such as will first be fully described, and specifically pointedout in the claims.

In the drawings, Figure l-is an isothermal View showing the range ofclosets or latrine with the. walls of the ventilating-chamber brokenaway, showing the discharge-basin, the receiver, and the downdraft-pipe,and the improved water trap and Valves within the basin in a closedposition. Fig. 2 is a vertical sectional view of the range-closets, theventilating-chamber, the receiver and-pipe, and the clean-out trap, asseen in Fig. 1. Fig. 3 is a cross-sectional View of the discharge-basin,showing the rear end wall, the hinge-plate or valve, and the trap. Fig.4 is a perspective view in detail of the end wall of thedischarge-basin, showing alternate hinged plates or valves in apartially-open position.

Similar letters of reference indicate corresponding parts in all thefigures.

Referring to the drawings, A A A represent separate range water-closetsemployed in apartments of public buildings and form what is commonlytermed a latrine, the seats of which closets are arranged in ahorizontal plane.

B represents the floor of the compartment in which the closets arearranged, and b represents the interior wall supporting one end of thefloor.

b is a partition-wall in a vertical line with the wall b, which formsthe inner side wall to the ventilating-chamber.

' O is the ventilating-chamber, and C is-the outer wall to said chamber.

The front and rear sides a 0L and bottom a of the basin or closet A incross-section is in one piece, the front side at extending from theupper edge of the basin A downwardly a short.

distance in a straight line, and thence continued in a singleoutwardly-curved line to form the bottom a" of the basin, the back a ofthe basin being inclined rearwardly and at an oblique angle to the frontportion a of said basin, as in the ordinary construction of theseclosets. The front and rear sides and bottom of the basins of theclosets A A A forming the latrine are continued in a longitudinaldirection from the sides a a and bottom a of the basin of closet A, theextreme far end of the basin a of the closet A extending through thepartition I) of compartment 0, so as to, form a continuous conduit .ofthe water to the trap hereinafter described.

The bottom of the basin in the closet A-is also depressed and extendedin a single outwardlycurved line in the longitudinal direction of andnearly the length of said closet. The bottom of the basin a and thebottom of the basin 0. is also depressed in the same manner as the basinof the closet A.

The closets A A A of the latrine are supported at a suitable heightabove the floor by the standards 19 b b 12 the standard b sup portingthe end of the closet A extending within the ventilating chamber C. The

height of the bottom of the latrine is increased 1 from the floor asbeneath the'basin or closet A and the other basins in a correspondingdegree in order to decrease the depth of Water in the basins and enablethe conduit to dis chargefully the sewage into the basin A In theventilating-chamber -O- is the dis charge-basin A which is composed ofthe front side a5, bottom a", and rear inclined side portion (1 theforward end of which portions of the said basin conform in dimensions tothe extreme inner end of the basin a of closet A of the latrine in thesaid chamber 0 and are rigidly connected with said basin. The bottom (1of the discharge-basin extends downwardly and rearwardly from the pointof com nection with the basin a, in a single curved line below the levelof the bottom of basin a", to the rear end wall a which extends upwardlyfrom the bottom a the corresponding height of the sides of the saidbasin A and from one side a to the other side a In the rear end wall ais an opening a of considerable width, and which extends to within ashort distance of the bottom of the basin in one direction and to withina short distance of the upper end of the said wall inthe otherdirection. x.

Upon the outer side of the wall a is a sewage-receiver G, which consistsof an upright circular case, upon one side of which, near the upper endof said case, is an extension 9 at right angles to the case G, in whichis an opening g, the sides of which extension are fitted to the sides ofthe opening a in the end a the lower side of which extension extendsdownwardly from the end wall a in a single curved line. In the upper endof the case G is an opening g in which is fitted one end of adowndraft-pipe g the other end of which pipe is exposed to the open-airshaft of the building. The lower end of receiver G ex tends downwardlyto the sewer-pipe H, leading to the street, and is provided with aflanged opening 9 which is connected with a like opening in thesewer-pipe.

On the inner side of the discharge-basin A and extending over theopening a in the end wall a is a valve D, which is hinged at the upperend by the hinge cl to the upper end of wall a In the valve D, at ashort distance below the hinge (1,18 an opening f for the sewage. To theinner side of the valve D is attached one end of a trap or elbow F,which extends around the opening f in said valve, the lower inner sideof which end portion of the elbow inclines downwardly at an acute angleto end wall g The other end of the elbow F extends downwardly nearly tothe bottom of the discharge-basin A In the ventilating chamber 0,directly above the trap F, is a pulley g \Vith the upper end portion ofthe trap F is connected one end of a chain, the other end of which chainis extended over the pulley g and upon said end is a weight i.

For the purpose of gradually diminishing the discharge of the water fromthe basin A I employ-the construction as seen in Fig. 4, in the end wallof which basin I make an opening d larger in dimensions than the openinga in the end wall a of the basin A said opening extending to within ashort disstance of the front side a, bottom a, and rear side a of thebasin A Extending over said opening is a valve D, which is hinged to theupper end of the wall 01 as follows: In the valve D is an opening e ofconsiderable dimensions and which extends through the upper end of thevalve in one direction and to a point in a downward direction ashortdistance from the lower edge of the valve and is comparatively narrow inwidth. Over the opening e extends a valve E. 111 the valve is an openingfor the sewage, which extends nearly to the upper end of the valve inone direction and to within a short distance of the lower edge of saidvalve, over which opening extends one end of an elbow or trap F, theother end of which trap extends downwardly in the direction of thebottom of the discharge-basin. In this construction the separate upperends of the valve D are hinged to the separate hinges (1 and d on theupper part of the end wall of the basin. The valve E is hinged at d to aportion of the end wall between the separate hinges d d and whichextends inwardly beyond the said hinges, thus permitting the closing ofvalve E over the opening e. The valve D and trap F are each providedwith separate elevating-chains K and L, respectively, which extend overseparate pulleys in the same manner as over the pulley g.

In the operation the basins of the closets A A A are flushed orfurnished with a supply of water, either in large quantities or in smallquantities intermittently, which flows into the basin of closet A fromits source and in seeking its level in the succeeding basins in theseries of basins is rapidly discharged into the basin A in the chamber0, carrying with it the sewage from each basin. In this operation theinflowing water will fill the basin A to the bend in the trap and thendischarge over the bend through the said trap. Should it rise above thebend in the trap, it will discharge through said trap as fast as thecaliber will permit until the water reaches the level of the bend, whichis the normal water-level. v

In order to free the discharge-basin from an accumulation of rubbish,which is frequently thrown into the basins and is prevented fromentering the trap F, the valve D is raised in position, as seen indotted lines in Fig. 2, and so held by the weight 2', thus enabling theentire contents of the basin A to be discharged into the receiver G andthence to the sewer-pipe H. The receiver G being water-tight, the valveD is kept closed by its own weight and the weight of the water againstit, so that the water, once started, will discharge the water in thebasin A until the water is lowered to its normal height.

In large'latrines it is important to lower the water in thedischarge-basin in degrees in order to recover articles of value whichwill finally be deposited in the discharge-basin A this beingaccomplished with the dischargebasin fitted with the valves and trap, asin Fig. 4, the ordinary height'of the water in the basin employing saidvalves being in excess of that in basin A with the valve D. In the formof the valve, as in Fig. 3, a certain amount of filtration or strainagemay be conducted before the final washout of the basin.

Having fully described my invention, what I now claim as new, and desire'to secure by Letters Patent, is-
